IMPROVED APPARATUS. FOR. VCQQLING LIQUIDS.

The Schedule referred toy in these Letters Patent and making part of the Bama.

To all whom 'it ma/y concern:

Be it knownpthat we, CHARLES GREENLEE and WILLIAM H. REDFLELD, of Belvidere, in-the county of Boone, and State of Illinois, have invented an Im- `pro`ved- Apparatus rfor Cooling Liquids; and we do hereby declare that the following isa full, clear, and exact description thereof', which will enable ,others skilledin the' art to` make and usethe same, reference `being `h ad to the accompanying drawings, and letters marked thereon, lmaking a part of this description, in

, j which..

Figuregl yis aperspective representation o f our ,invention.- f g Figurel, `a transverse sectional elevation of the same, with the supporting-frame removed. l

The nature of the .present vinvention consists, in

general terms,'in the novel construction of a two-part tank, which receives the liquid to be cooled, and the' cooling-material, and operates with a corrugated'cooll ing-"surface, the lower `end 'of which is provided with spouts, to conduct the liluids into `suitable receptacles.

H represents a-semicircular tank, which is made of metal or other suitable material, and divided into compartlnentsF G,'by means of a partition, I, and which is so arranged as to be held in place by a rim, b b b b, f bearing on a substantial frame, A A. 'A recess is formed iu the bottom of the tank, adjoining the partition I, by meansl of anrinclined plate, PJig. 2, secured :to said partition and to the ends of l the tank. p p

The object of this recess is to allow the upper end of aoorrugated plate, S, so to extend above the openings in the bottoms of the apartmentsF G as to pre l, `vent the fliquid `to be cooled from mixing with the lcooling-substance.` l

`The plate S is made of any metal which will not corrode, and it is so bent or corrugated as `to give a 3 large cooling-surface in a short space, as shown in both figures, and it terminates at the bottom in spouts D E, and has its ends fastened to plates A', supported by the frame A.

These plates have grooves T formedvin their edges, to catch any liquid which might otherwise be wasted, and conduct it into the troughs D E, projecting iauges `V being used on one side rof the plate S, to complete I the channel to the trough D..

A gate, L, is arranged to-operate in guides M N, by means of a lever, J, pivoted to it, and to the partition I, at K, and it has a series of holes, a c, 8mo., made through it, corresponding iu number'to the lnumber of -holes made through the lower angle of the apartment G, by means of'which'the flow of cooling-substance is controlled.

Operai/ion.

The liquid` to be cooled is placed in the" apartment` I F, and the cooling-liquid in theapartment Gr, and as the former passes through holes in the lower angle of the apartment F, and down, in a thin sheet, over one sideof the corrugated plate S, and into the spout E,

the cooling-liquid passes down the other side, and thus reduces the temperature of the liquid to be cooled,

correspondingly to the cooling-liquid.Y

Having `thus fully described my invention,

What I claim, and desire to. secure by Letters Pat vent of the UnitedStates, isl The tank, provided with apartments F G, in combination with plate A,'provided with grooves T, and

corrugated plate S', provided with troughs D E, and gate L, as described.
